"I know I'm being the Grinch," said Maynard Thurfield, a local AM radio host whose son attends the school. "I just think it's sending the complete wrong message. I think what it directly says is this sporting event — which at the end of the day is something we watch on television — is more important than going to read and write in the morning."

Ira Miller, who runs the Rotunda Cinemas in Baltimore, said the theater will show two matinees on Sunday and then close for the day, "because with the game, we're not going to compete against that."

"We get destroyed on the Super Bowl even without the Ravens playing," Miller said. "It's an imposition, but it's like having a snowstorm. Everybody in Baltimore is going to be watching that game," including him. "I'm the world's biggest Ravens fan. We love our Ravens. I'm wearing purple right now."

Some independent restaurants also are closing early. Il Basilico, an Italian restaurant in Timonium, said it would close at 5 p.m. on Sunday, instead of the typical 11 p.m.

"Football is very important and we have no TVs," Vince Culotta, general manger of the Iron Bridge Wine Company in Columbia, said of the restaurant's decision to close at 4 p.m. after a Super Bowl-themed brunch.. "The first couple years we were open we gave it a shot — very few people showed up. When I say very few, I mean nearly zero."

He added: "I think any place that has a TV will probably stay open."

Indeed, even as some businesses scale back hours, others are extending them to capture Ravens-fueled revenue.

Several area sporting goods stores plan to open after the game in the event of a win, so shoppers can buy commemorative apparel.

For example, Dick's Sporting Goods in White Marsh will unlock its doors "as soon as time expires" if the Ravens are victorious, Bardzik said.

The store will remain open until 2 a.m. — or until the rush calms down — and reopen at 6 a.m. Patrons can shop for Ravens apparel immediately following the game, but the rest of the merchandise will be blocked off, Bardzik said. She didn't know how many employees would be called in but said the store expects large crowds.

Modell's Sporting Goods on Reisterstown Road in Baltimore also plans to reopen Sunday night if the Ravens win. All of the store's merchandise will be available for purchase, but assistant manager Mike Milazzo said he expects the bulk of the sales to be Ravens-related.

He said the store will open as quickly as the staff can get championship merchandise set up and will stay open until business slows.

"I have my people in place," he said, laughing.

Sports Authority Sporting Goods stores — including locations in Baltimore, Towson and Laurel — will also open Sunday night if the Ravens win and reopen at 6 a.m. Monday.

Despite the excitement surrounding the game, not all local sporting goods stores will be unlocking their doors to celebrate a Super Bowl win.

"Oh, not us," said Geri Durham, co-owner of The Sport Shop at Harborplace.

She plans to be at home watching the game but said the store will open around 8 a.m. Monday to sell championship T-shirts.
